INSOMNIA CAN OCCUR DUE TO MANY REASONS SOME OF WHICH I HAVE LISTED BELOW;

* Depression, worry, exams, emotional problems ,anger or grief.

* Environmental noise (noisy neighbours) or a partner who snores!

* Worrying about whether or not they will actually be able to sleep whenever they go to bed. If they fail to sleep that night, then worrying about what will happen the next night, and so on.

* Moving house or employment, changes in work shifts.

* Jet lag.

* Pain or a medical condition (one of the most commonest causes) drug use or withdrawal. Smoking.

* Medication - including some contraceptives, slimming pills, stimulants, diuretics, or even sleeping pills themselves.

* Waking up in the early hours and not being able to fall asleep again, or falling asleep and then waking up after a few minutes, then falling asleep again only to wake up once more, with this cycle repeating itself throughout the night.
